CustomCompassPins fires callback "OnWorldMapChanged" and error occurs in callback handler. Is it really CustomCompassPins fault?

Error occurs in this function:

function ZO_WorldMapFilterPanel_Shared:GetPinFilter(mapPinGroup)
    if self.modeVars then
        return self.modeVars.filters[self.mapFilterType][mapPinGroup]
    end
    return nil
end

Because self.modeVars.filters[self.mapFilterType] is nil.
(In this case self = WORLD_MAP_FILTERS.imperialPvPPanel and self.modeVars = self.savedVars[mapMode])

I wonder if it is because ZO_WorldMap_GetMode() returns invalid value (mapMode is invalid or nil). But I can't be sure unless I do some tests.
